The 2013-2014 school year involved preparation for implementing the new US Department of Agriculture (USDA) competitive foods nutrition standards. An awareness of associations between commercial supplier involvement, food vending practices, and food vending item availability may assist schools in preparing for the new standards.
Analyses used 2007-2012 questionnaire data from administrators of 814 middle and 801 high schools in the nationally representative Youth, Education, and Society study to examine prevalence of profit from and commercial involvement with vending machine food sales, and associations between such measures and food availability.
Profits for the school district were associated with decreased low-nutrient, energy-dense (LNED) food availability and increased fruit/vegetable availability. Profits for the school and use of company suppliers were associated with increased LNED availability; company suppliers also were associated with decreased fruit/vegetable availability. Supplier "say" in vending food selection was associated with increased LNED availability and decreased fruit/vegetable availability.
Results support (1) increased district involvement with school vending policies and practices, and (2) limited supplier "say" as to what items are made available in student-accessed vending machines. Schools and districts should pay close attention to which food items replace vending machine LNED foods following implementation of the new nutrition standards.
2013 - 2014学年涉及为实施美国农业部(USDA)新的竞争性食品营养标准做准备。了解商业供应商参与、食品自动售货实践与食品自动售货商品供应之间的关联,可能有助于学校为新标准做准备。
分析使用了来自全国代表性的青年、教育与社会研究中814所初中和801所高中管理人员的2007 - 2012年问卷调查数据,以研究自动售货机食品销售的利润情况和商业参与程度,以及这些指标与食品供应之间的关联。
学区利润与低营养、高能量(LNED)食品供应减少以及水果/蔬菜供应增加相关。学校利润和公司供应商的使用与LNED食品供应增加相关;公司供应商也与水果/蔬菜供应减少相关。供应商在自动售货食品选择方面的 “话语权” 与LNED食品供应增加和水果/蔬菜供应减少相关。
结果支持(1)学区更多地参与学校自动售货政策和实践,以及(2)限制供应商对学生可使用的自动售货机中供应商品的 “话语权”。学校和学区应密切关注在新营养标准实施后,哪些食品取代了自动售货机中的LNED食品。
